If anyone’s curious, the first step is wrong. e^x minus its integral is a constant. Not necessarily zero.

Ok. Take the derivative of both sides and integrate at the end, then plug in a value of x to get C = 0.

In step two you can't gake out e^x from the integral because is being integrated by the x variable.
